FIREPROOIE BUILDING CONSTRUCTION.

Application flied May 1, 1916.

To all whom t may concern:

Be it known that I, CHARLES W. YOUNG, a citizen oi the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Fireproof Building Construction, of which the following is a specification.

This invention relates to an improvement in a lire proof construction for the walls and floors.

One of the objects of the invention is to employ such a construction that floors and partition walls, including door bucks, may be more quickly built than ordinary after the concrete or tile substructure for the licor has been molded or completed.

Another object is to provide an intermediate, ire-proof filler which will support the wood iioo'r strips uniformly and will provide compartments operating to advantage to prevent lire from spreading, will tend to deaden sounds or vibration incident to the use ci' wood floors, will not be injured by the expansive force of heat and will provide a firm support for the door bucks.

Still another object is to provide such a construction that floors and partitions of tire proof buildings may be more conveniently and economically built than ordinary, and that the parts employed, while discharging all required functions, may be few and simple.

In the drawing which illustrates the improvement, Figure 1 is a perspective View showing parts of a Hoor, partitions and a door buck, embodying the invention, parts being broken away and in section. Fig. 2 is a view in side elevation of one of the fire-prooi supporting strips employed. Figs. 3 and Il illustrate parts of partition walls in transverse section, showing facility for the mounting of base boards and picture molding by use of the fire proof strips with which the partitions are provided.

For the purposes mentioned, lire-proof supporting strips 5, best shown in Fig. 2, are employed, these being rectangular in crosssection and of any suitable length, width or thickness, as may be required. Each consists of a wood core 6 into which nails may be driven or in which screws may be secured, and thereby operate as nailing-strips when laid in a wall for supporting the various kinds of interior iinishings, as the base boards, one of which is indicated at 7 in Fig.

3, or the picture molding 8 shown in Fig. 4, or the floor strips 9 shown in Fig. 1. In order that said members 5 may be rectilinear they are formed in molds. The wood cores 6, which are iirst thoroughly water proofed, are then immersed in a mixture of plaster of Paris and water. They are then wrapped with hemp, jute, cloth or light wire-cloth to provide an intermediate cover or layer 10, the outer surface of which is also coated with the mixture, and a non-conducting envelop or jacket 11 is then provided of any suitable thickness, consisting of adhesive material with which a flexible iller has been mixed, such as hemp, jute, sisal or a limited quantity or" excelsior or saw dust, the adhesive material mentioned for said jacket consisting of gypsum plaster, gypsite, plaster of Paris or Portland cement. The lire-proof supporting strips thus provided are used for all of the purposes herein to be described, and they are portable and convenient in use, will not shrink, and resist the action of lire to advantage.

In the construction of fire proof buildings `there is generally provided a fire proof substructure 12 either of concrete or tile, upon which the Hoor and partitions are supported. To provide a suitable support for the floor strips 9, a single reticulated layer is deposited on the base 12, consisting of widely spaced, relatively narrow, adhesive strips, beds or parts, indicated respectively at 13 and 13., the parts 13 being disposed parallel with reference to each other and the parts 13 being disposed transversely with reference to the parts 13, the ingredients and proportions employed being two parts, in bulk, of gypsum plaster and three parts of clean, coarse sand, these being mixed with water to make a semi-plastic mortar which will readily adhere to the base 12. Upon each parallel part 13 oi said reticulated layer is disposed one oi the tire-proof supporting strips mentioned, thesek being designated, for convenience, at 5a, and on account of the construction as described, they will adhere to the parallel parts 13 of the reticulated layer.

` At 5b are indicated tire-proof cross-strips, these being disposed on the transverse parts 13 ci' the reticulated layer. The comparatively short strips 5" are produced, generally by sawing the strips 5 into suitable lengths or sections, and on that account, and to the end that the wood cores 6 will be covered, a liller 14 of the adhesive mortar is placed between the ends of the sections 5b and the sides of the supporting-strips 5a, so that the ends of the Wood cores of these sections Will not be exposed to the action of fire.

As thus described, numerous compartments having imperforate Walls and practically of uniform area are provided immediately below the floor strips, tending to prevent spreading of fire; the supportingstrips and supportingstrips or sections 5b also, by this arrangement may be disposed in a plane to provide a uniform support for the floor strips, contact of the floor strips with the base 12 will be prevented and the cores 6 Will be protected from the corrosive action of the base 12 if said base is constructed of concrete, the cement used in the concrete generally causing injury to Wood if remaining in contact therewith a considerable period of time.

ln the building of fire-proof partitions all wood may be eliminated except the Wood cores G of the strips 5. As shown in the drawing, strips 5 may be used in the partitions, each having any desired length or thickness, the Width preferably being substantially the same as the Wall tiles 16.

For rectangular door bucks 17 I provide a base consisting` of a strip 5, other strips respectively indicated at 5e and 5f being employed for the sides and top of the door buck, these parts, being secured together, as required, by keepers 1S, and suitable tieplates 19 being' used for connecting the sides of the door buck to the tiles. The strip 5d or base of the door buck is placed upon the comparatively Wide part 13 of the rectilinear layer above mentioned and the tiles for the partition abut upon the side strips 59, a pair of parallel strips 5g being employed and disposed at the sides of the base 5d which provides a firm support against side movements of the door buck, and which as shown in Fig. 1, support the ends of the floor strips 9, all of said strips for the door buck and the parallel strips 5g being of the same material. and constructed in the same manner as the strip heretofore particularly described, and shown in Fig. 2. The door buck provides a fire-proof construction for all door openings, and since the fire-proof strips therefor have an adequate Width, they providev suitable supports to Which other parts may be conveniently secured.

Among some of the advantages to be derived by use of the invention, it may be stated that the floors and partitions, includ ing door bucks, may be quickly built or placed in position as soon as the base 12 for the floors have been constructed, all parts except the floor strips 9 being fire proof and protected from any injurious action of a concrete base, and the parts being few, may be economical in construction.

Having fully described my invention,
